Description
本發明係有關於一種扭力扳手。The invention relates to a torque wrench.
按,一般扭力扳手通常係可供設定扭力值大小,使其可對應各種構件的組裝、拆卸過程而選擇適當的扭力設定值,習知扭力扳手之本體一端設有一驅動頭部,扭力扳手之本體另端內設有一中央推桿以調整扭力設定值,且在該端裝設一可調動之轉動件,當轉動轉動件時中央推桿會被轉動件帶動以進行軸向移動,進而達成調整扭力扳手的扭力設定值,接著使用者便可進行鎖設作業,專利號TWM540019所述之專利即屬此類,為了避免轉動件任意轉動,該轉動件可沿該軸向滑動於一鎖定位置及一解除位置,當位於鎖定位置時該轉動件之卡齒與該本體之卡齒相卡抵,該轉動件即無法轉動,欲調整扭力值時需先將該轉動件移動至解除位置,使該轉動件之卡齒與該本體之卡齒不相卡抵,方可轉動該轉動件。Press, the general torque wrench is usually available for setting the torque value, so that it can be selected according to the assembly and disassembly process of various components, and the appropriate torque setting value is selected. The body of the conventional torque wrench has a driving head at one end, and the body of the torque wrench The other end is equipped with a central push rod to adjust the torque setting value, and an adjustable rotating part is installed at this end. When the rotating part is rotated, the central push rod will be driven by the rotating part to move axially, thereby achieving the adjustment of the torque The torque setting value of the wrench can then be locked by the user. The patent described in Patent No. TWM540019 belongs to this category. In order to avoid arbitrary rotation of the rotating part, the rotating part can slide along the axial direction to a locked position and a locking position. Release position. When in the locked position, the teeth of the rotating member and the teeth of the main body are engaged, and the rotating member cannot be rotated. If you want to adjust the torque value, you must first move the rotating member to the released position to make the rotation Only when the teeth of the piece and the teeth of the body do not engage with each other, the rotating piece can be rotated.
然而,習知扭力扳手使用一段時間後,轉動件容易鬆脫而造成任意相對該本體滑動,如此在使用該扭力扳手之過程中,轉動件容易不慎自行移動至解除位置,而導致該扭力扳手之扭力設定值改變,造成作業上之誤差,存在急待改善之缺弊。However, after the conventional torque wrench is used for a period of time, the rotating part is easy to loosen and cause any sliding relative to the body.
